When you enable Disappearing Messages, you can set messages to disappear 24 hours, 7 days, or 90 days after the time they are sent. If a user doesn't open WhatsApp in the 24 hour, 7 day, or 90 day period, the message will disappear from the chat.
Why is my WhatsApp deleting my voice messages?
Why do my Voice Messages stop recording after 9 or 10 seconds? This issue is caused by an interference with the multi-touch functionality on the screen of your phone, either by a case or by some sort of film or screen protector. Please remove all accessories from the phone and try this feature.
How do you know if someone has listened to your voice note on WhatsApp?
In a group chat, the second check mark will appear when all participants in the group have received your message. Two blue check marks will appear when all participants in the group have read your message.
Is there a limit on WhatsApp voice message?
The maximum file size allowed for all media (photos, videos or voice messages) to be sent or forwarded through WhatsApp is 16 MB on all platforms. On most phones, this will equal from about 90 seconds to 3 minutes of video.
